“…Simulated increase in average N concentration in tile drainage due to LSNT compared to SA was only 0.1 mg N L − 1 while the observed difference was 0.8 mg N L − 1 . SA and LSNT under the CS and SC rotations and CP and NT tillage treatments from 1993to 1998. Bakhsh et al (2000 reported significant increases in corn yield due to LSNT compared to SA for CP and NT treatments for corn in CS and SC rotation in the Nashua experiments, but their analysis could not ascertain if the yield response was caused by timing or rate of N fertilization.…”

“…Four out of ten measured corn grain yields were higher under SA compared to SM treatment and six were lower. These inconsistent results indicate that the effect of SM treatment on corn growth depend not only on its nutrient (e.g., N and P) content but also on changes in soil hydraulic properties (porosity, water retention, and aeration) induced by the addition of the organic matter (manure) (Fleming et al, 1998). Singer et al (2004) reported increased grain yields under swine manure treatments compared to organic N (SA) but suggested the effect was not necessarily due to soil N changes.…”

The objective of this study was to explore if more crop-specific plant growth modules can improve simulations of crop yields, and N in tile flow under different management practices compared with a generic plant growth module. We calibrated and evaluated the Root Zone Water Quality Model (RZWQM) with the Decision Support for Agrotechnology Transfer (DSSAT v3.5) plant growth modules (RZWQM-DSSAT) for simulating tillage (NT -no till, RT -ridge till, CP -chisel plow, and MP -moldboard plow), crop rotation {CC -continuous corn, and CS -corn (Zea mays L.)-soybean [Glycine max (L.) Merr.]}, and nitrogen (N) (SA -single application at preplant, and LSNT -late spring soil N test based application) and manure (SM -fall injected swine manure) management effects on crop production and water quality. Data from 1978 to 2003 from a water quality experiment near Nashua (Nashua experiments), Iowa, USA, were used. The model was calibrated using data from one treatment plot and validated for the rest of the plots. Simulated management effects on annual N loading in tile flow were agreeable with measured effects in 85%, 99%, 88%, and 78% of the cases for tillage, crop rotation (CS vs. CC), N application timing (SA vs. LSNT), and swine manure applications (SM vs. SA), respectively. On average, the LSNT plots were simulated to have 359 kg ha − 1 higher corn yield compared to SA, when the observed increase was 812 kg ha − 1 . Grain yield simulations were not sensitive to differences between RT and NT, between SM and SA treatments, and between CS and CC. We conclude that considering the uncertainties of basic input data, processes in the field, and lack of site specific weather data, the results obtained with this RZWQM-DSSAT hybrid model were not much better than the results obtained earlier with the generic crop growth module.

“…We used a model developed by Fleming et al (1998) to estimate the costs of moving manure to the amount of land necessary for meeting a nutrient standard (Fleming et al, 1998;Ribaudo et al 2003). This model estimates the net costs of spreading manure while accounting for the economic benefit of replacing commercial fertilizer with manure nutrients and for the availability of suitable land in the surrounding countryside.…”

“…Progressive legislation may recognize that the application of manure to land is an established and recommended practice (Illinois Compiled Statutes Annotated, 2001) and proceed to delineate criteria to advance sustainability. By incorporating sustainable ideas in regulations governing animal wastes, further encouragement might be given to help producers recycle nutrients from manure as a production input (Fleming et al, 1998;Sheffield, 2000).…”

Animal feeding operations have come under increased scrutiny as sources of water pollution. Due to the concentration of animals at individual locations and in certain regions, the local environment may not be able to use all of the nutrients contained in the manure. Particularly, problematic are waters being impaired by nitrogen and phosphorus from animal manure. Since federal and state regulations have not been totally successful in precluding water contamination from manure nutrients, scientists and policymakers might seek ways to encourage the use of manure as a resource for crop production. By analyzing diverse state regulations, this paper identifies several strategies that would treat animal waste as a recyclable production input rather than a production byproduct. Citizens and regulators can encourage more sustainable livestock production by proffering regulations that mandate selected production requirements or practices. Agronomic rate regulations, limitations on manure application and timing, lagoon safety requirements, closure mandates, and alternative uses of manure constitute possibilities to remedy some pollution problems.
